The three statements that correctly describe the lifestyle of the earliest humans such as Homo habilis are:
- They made use of tools and weapons.
- They hunted animals and probably scavenged food left by other predators.
- They lived in groups of 10-12 adults and their children.
Homo habilis is known for being one of the first species to use tools, likely engaged in scavenging as well as hunting, and is believed to have lived in small social groups. They did not tend to settle in one area to raise crops, nor did they spend more time in trees than on the ground.
